we keep local (on our web box), networked (NFS) and S3 backups of a) our entire server build, b) our code base, c) our database dumps, d) our email & configs. we backup nightly (we backup at the "quietest" period of last nights activity on the subsequent night) on our local machine we can keep: yesterdays backup, day before yesterday, end of last week, and start of month backups. it's entirely automated, except for the bi-monthly backup check (I CANNOT STRESS THIS ENOUGH - CHECK BACKUPS!) where we fully restore our data and code on a spare box. by code i mean live code - we also backup our git working code base.
